Be it known that I, JOHAN S. KLEIN, a citizen of the United States,residing at Oil City, in

the county of Venango and State of Pennsyl- 5 Vania, h ave invented newand useful Improve ments in VVlTater-Cooled Rods and Pistons, ot whichthe following;r is a specification.

This invention relates to water-cooled rods and pistons; and it consistsin certain improve.-

xo ments in the construction thereof, as will be hereinafter fullydescribed, and pointed out in the claims.

- The purpose of the invention is to cool rods and pistons ordinarilyused in gas-engines,

I 5 and more particularly a rod used on multiplecylinder Agas-engines.

The invention is illustrated in the accoml panying drawings, as follows:

Figurejl shows a central longitudinal seczo tion ofthe device; Fig. 2, asection on the line 2 2 in Fig. l; Fig. 3, a development of the sur`face of the core of a rod. i,

A marks the rod, .vhiehieomprises the core a and outer shell or tube a.The core is pro- 25 vided with .the Webs o2, which form grooves betweenthem through which the Water may pass. These Webs are in contact withthe shell or tube a and stiften the rod as well form the separatechannels. The tube a be- ;o ing very thin, water in the passages formed35 B operating in one cylinder and the piston l din a'second cylinder.(These cylinders are not shown.) Water is admitted at one end of the rodthrough the pipes C C' and is expelled from the red through the pipes DD". The

4o rod is attached, by means of its core, to the part of the cross-heador other device F. by any usual means. The pistons are provided withpassages through which Water from the rod circulates.l l

One of the important features of this invention is that separatepassages lead to the separate pistons, thus compelling a completecirculation in the rofl` as well as a separate ci reulation for eachpiston.' By this means the eir- 5o culation for eaehlpiston maybe socontrolled as to keep it properly cooled. The scheme of is connectedwiththe lower end of the piston i B by means of the passage b. The waterpasses. into the hollow Z2' of the piston, ont by the passage' L2 ot thepiston into the passage (L5, and out by the pipe D. lIt will be notedthat the passages wie" are separated from the part ofthe rod beyond thepiston B by means of the cross-partitions a am. The water entering thepassage ci through c' is conveyed by that passage tothe piston B. Theweb c2 at the end of this passage is cut at a, and the water isconducted in the double passage ala? to the piston' l'. It passes fromthe passages ci ai by means of the passa-ge b3 of the piston into thehollow h4 of the piston, and from this hollow liv-the passage b5 throughthe passages afz a? and passage al" to the'outlet D'. A'passage aiconnects the passages@R as. The pnrpose of spreading the Apassage at isto deliver water to the entire surface of the rod A between the pistons.The passages ai c7 accomplish this on the intake and the passages a a.on the exit end of the circuit. Any number of passages may be provided,and any number of pistons may be handled in the same Way by simply,`connecting a suiicient number of passages at each piston to conveycooling fluid to the rod beyond this piston. Y

l y 1n akin 5.; one of the passages leadingto the piston i; or if extendto near the bottom of the hollow b' or hi the piston may be emptied hypressure through the other passagcor by attaching a pump to the passagesdirectly connected therewith. ture where there is danger of freezingwhen the engine in which it is placed is out of use.

Nhat I claim as new is- Y l. A water-cooled rod comprising a web, core,and a tubular shell, the shell contacting withthe edges of the Webs andforming separate channels4 for the passage of Water between the shelland the core.

A water-cooled rod comprising; aweb,

core, and a tubular shell, the shell contacting with the edges ofl thewel) and forming separate channels for the passage of water bnf tweenthe shell and the core, in combination This is an important fea- IOOwith connecting-passageswhereby waterinay be made to traverse the rodand be introduced into and expelled from the sainepoint of the rod.

3. The combination of a plurality of pistons; a rod connecting them;asource of fluid supply and exhaust; and passages through the rodindependently connecting the pistons with said supply and exhaust.

4. The combination of a piston; a rod on which said piston is mountedhaving apassage leading to said piston; a separate passage leadingthrough said piston to a second piston mounted on said rod; and saidSecond piston.

5. The combination of a piston; a rod on which said piston is mountedhaving a passage leading to and from'said piston; separate passagesleading through said piston to and from a second piston mounted on saidrod; and said second piston.

(i. The combination oi' thepiston, a rod exi tending through saidpiston, said lrod being provided with a passage leading to and from isaid piston, and an independent passage. leading through said piston toa part of the rod beyond said piston, said passage leading through thepiston being extended circumferentially at or near the piston.

7. The combination of a piston having passages leading nearthc bottomthereof ;l a rod on which said piston is mounted having passagesconnected with said passage in the piston.

8. The combination of the piston B, having the hollow b; passages b b2,therein; the pis-v ton B, having the hollow b", and passages b3 bi",therein; the rod A, comprising the vcore a, having the web a2, formingthe pas sages c3 a5, connected with the passages l) b2 respectively, thepassages a* am, by passages a a, the passages a7 as, connected with thepassages b3 b5; and the shell a', on said core.

Intestimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
